Merav Opher

Opher was born in Israel and lived there until 1978 when she moved to Brazil with her parents. In 1992 and 1998, Opher received her B.S. in physics and her Ph.D. in physics and astronomy from the University of São Paulo. Following her Ph.D., Opher was a postdoctoral investigator at the University of California, Los Angeles from 1999 until 2001. She was a Caltech Scholar at NASA's Jet Propulsion Laboratory and at University of Michigan from 2001-2004. She was on the faculty of George Mason University from 2005 until 2010, at which point she moved to Boston University, where she was promoted to professor in 2020. Opher is the director of the SHIELD DRIVE Science Center at Boston University, a project funded by NASA that will study the shape of the heliosphere. She has served on the Space Studies Board at the National Academy of Sciences which evaluated the progress of space and solar physics. ==Research==

Her research interests include computational and theoretical plasma physics in space and astrophysics, interaction of the Solar System with the interstellar medium, solar wind, and shocks in the lower corona, T-Tauri and Solar-Like Stars. In 2001, Opher began work on the heliosphere while she was a postdoctoral student at the Jet Propulsion lab. Her researcher focuses on how the solar wind shapes the heliosphere, the protective atmospheric shield between Earth and the rest of the galaxy, where she has shown the shape of the heliosphere is similar to a croissant and not a comet with a tail as previously thought. Opher's 2020 paper expanding on the crescent shape of the heliosphere was published in Nature Astronomy, featured on the cover of the July 2020 issue, and covered by the media. In 2021, Opher's research revealed that the stability of the heliosphere originates from the neutral hydrogen particles that interact with the heliosphere. Opher has written in The Hill about the dangers of space tourism for people where she describes the radiation coming through space and the need to better understand how the heliosphere filters this radiation before people can travel safely to other planets. As of 2021, Opher's research has been cited more than 4400 times and she has an h-index of 37. ==Honors and awards==

In 2008, Opher received an NSF Young Investigator Award, and she was named a Kavli Fellow by the National Academy of Sciences. ==Selected publications==
